#### Terms in this set (...)

base
In exponential notation, the number or variable that undergoes repeated multiplication. In the diagram, the "a" is the _?_.
exponent
In exponential notation, the number of times the base is used as a factor. In the diagram, the "m" is the _?_.
integers
The numbers ... -3, -2, -1, 0, 1, 2, 3 ... .
positive number
A number greater than zero.
standard notation
A way to write numbers by using digits. Example: 254 = 2 hundred fifty-four.
power
An expression in the form depicted below or the value of such an expression. Example: 2 to the fourth power = 16.
rational number
A number that can be written as the quotient of two integers.
real numbers
The set of _?_ numbers consisting of the positive numbers, the negative numbers, and zero. The _?_ numbers can be thought of as the set of all decimals, finite or infinite in length.
scientific notation
A method of writing very large or very small numbers by using powers of 10.
whole number
The positive integers together with zero. Example: 0, 1, 2, 3, 4 ... .
Zero Exponent Property
A nonzero number to the zero power is 1.
Negative Exponent Property
